Cause / Solution
House indicator light

(latched). BD2 & BD3
MODELS ONLY
Verify that the relay is actually in the engaged
(latched) state. With a test light, probe the larger
5/16” stud terminals on each side of the relay. Both
terminals should be powered up in the engaged
(latched) state. If only one is powering up the test
light go to step 1. If both 5/16” terminals are
powered up go to step 43.
STEP 42
Check fuses on relay
. If not blown go to step 44, if
blown replace with size fuse and retest. If fuse / fuses
re-blow go to step 9.
Remove the battery disconnect panel from cabinet
/ console and with a multi-meter set on DC
voltage, measure between the green wire at pin # 5
and the black wire on pin # 6. The voltage should
read whatever DC voltage as the batteries read
(typically around 12 volts). If it reads 0 VDC then
inspect the harness for damage, or replace harness,
refer to PARTS LINK #1 (page 7). If the voltage
reading is the same as the nominal battery reading
then replace battery disconnect panel, refer to
PARTS LINK #2 (page 8)
